What you should do is go to http://www.rototimes.com and use their 2005 projections dollar value calculator (since the 2006 projections aren't synched up yet) to see the difference in values for an 18-team league and a 12-team league. My suggestion: Figure out what each of these players would be worth in the 18-team league and the 12-team league:
$50 player (if there are any)
$40
$30
$20
$10
$1

That can give you a ballpark of what equates to what. My guess is that the highest $ players will drop a little in value, and those at $1 will now be worth ~$10 since there's 150 more players to go after.

The 18 team, 23 player part is handled just fine at most sites, but the 17 bench spots are going to be a little tougher.

Most of the rags out now are advertising over 600 player profiles. You are going to need over 700. Plus I am sure that part of the 17 bench spots will be prospects, so you may need multiple sources. A top 100 prospect list will help.

I love drafting and playing, but a 40 man roster seems like a bit too much to manage effectively. Plus, 18 teams, that is deep. Best of luck...
